just seems nicely balanced.
this is what USN should get if they, or someone else, really wants "shore bombardment".
155mm/6' is the Goldlocks size for reasons, and range of today's 6' would do for WTF shore bombardment is really about, dominating the first few miles inland, and 12 fast firing 6' makes more sense than 9 very slow firing 16".
At least an old light cruiser would also be expendable.
